In severe trauma, conventional scanning methods such as Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) can detect bone rupture, edema and micro-haemorrhages, but in mTBI, it is often difficult to detect edema or micro-hemorrhages, and the conventional methods is often not sensitive enough to show pathology especially beyond the acute period, although patients continue to have physical symptoms as well as cognitive and emotional problems (6, 12).
